More than 500 registered voters were questioned for the survey. Brown received 49 percent of their support, while Warren got 41 percent.

Ten percent of the voters were undecided.

“Independent voters tend to decide these races. They’re the largest block of voters in the state, and among independent voters, Brown has a lead of 58-29 percent,” said Tim Vercellotti, the director of polling at Western New England University

However, there’s a lot of wiggle room in the latest poll. It also finds that 31 percent of voters said they may change their minds before Election Day.
